Leading efficiency wideband transmitters Leading efficiency wideband UHF TV Transmitters Doherty Technology Transmitter s energy efficiency is a key factor for network operators by the time of selecting TV transmitters. The main reason is the energy cost, since after ten years of operation it can represent up to three times the initial investment. With the adoption of Doherty Technology in TV transmitters it was possible to boost energy efficiency values up to 42%, representing an improvement of almost 50% over traditional technology transmitters. Furthermore, higher energy efficiency leads to an enhancement of other important aspects that also have an impact on the network cost. By dissipating less energy, the cooling system load is reduced and so the transmitter form factor. Thus, more amplifiers can be integrated in a single rack. In other words, more power in less space. Despite all its advantages, classical Doherty topology has an inconvenient: It is an inherently narrowband technology. It involves that so far, the power amplifiers had to be precisely adjusted to work optimally in their RF channel. Therefore, when a channel change was requested, the network operator had to modify the power amplifiers or replace them with new ones. Obviously, this also greatly complicates the maintenance tasks, management and logistics of spare units.

Leading efficiency wideband transmitters Wideband advantages The TUWH4000 series, equipped with wideband Doherty technology, overcomes the drawbacks of classical Doherty transmitters while keeping all the benefits. Thus definitively ends with trade-offs. You don t need to waste frequency agility to optimize energy efficiency. TUWH4000 transmitters reach an energy efficiency of up to 38% for COFDM and 42% for ATSC waveforms. The efficiency is maintained throughout the UHF range, so no adjustment is required in the power amplifiers at the time of changing the RF channel of operation. Moreover, with the wideband technology there is only one reference for the power amplifiers, which drastically simplifies the management of spare parts. An example that illustrates the benefits of wideband Doherty amplifiers is the N+1 configuration. With classic Doherty technology, each main transmitter must be perfectly adjusted to its transmission channel in order to get the maximum efficiency. On the other hand, the reserve transmitter must be able to replace any of the main transmitters. Therefore, it can not work in Doherty mode and its energy efficiency is lower. As a consequence, the design of the power supply network of the entire system becomes more complex. Moreover, it is necessary to handle different types of power amplifiers, depending on they are for main or reserve transmitters. Since all TUWH4000 transmitters comprising an N +1 system are identical, mains and reserve, the power consumption of the whole system is optimal and homogeneous. Furthermore, working with just a unique reference leads to reduction in the maintenance and logistics cost. Economic benefit The high energy efficiency of the TUWH4000 transmitters provides an immediate economic benefit to operators. As an example, taking a transmitter of 2.4kW with a standard efficiency of 25% as the basis and considering the average price of industrial energy in Europe (0.1215 / kwh), then the cost related to the annual consumption is approximately 10500. The same transmitter operating in high efficiency mode and featuring additional techniques for crest factor reduction may reach an efficiency of 40%. This means that in this new situation, the cost of the annual consumption of the transmitter is 6600. Therefore, the savings are approximately 4.000 per year. What is more, as increasing the number of transmitters in the network and the higher is their output power, the highest economical saving. We can conclude that network operators save money as soon as the TUWH4000 transmitters enter in operation. Efficiency optimization throughout the UHF band Máximum Efficiency TUWH4000 Series transmitters as part of N +1 system, main and reserve, are identical. The associated cost with equipment replacement is reduced and simplified. CH 1 CH 2... N-1 N 470 MHz UHF Band 800 MHz Egatel TUWH4000 Series v.1.3 2
Multiple configurations, full flexibility Multiple configurations, full flexibility To increase the flexibility of the equipment and to match the customer needs, the transmitters can operate without an exhaust air unit. If the exhaust air unit is used, then exciter or CCU9000 Control Unit monitors the operation of the cooling system. TE9000 Series Exciter Advanced integrated features Compact Design The TUWH4000 series provides maximum versatility and flexibility. Customers can choose from a multitude of different configurations to get the one that best suits their needs. The use of LDMOS-50 volts transistors technology and the optimum design of the amplifier stage yield in an excellent power density, allowing each amplifier to deliver an output power of 600W for COFDM standards an 1070W for ATSC in just three height units. A single rack of 42U can accomodate up to six transmitters or a 4+1 redundant system. The 600W COFDM (1070W ATSC) transmitters can be ordered without a rack for being installed in any existing in the transmitter site. Moreover, all the additional elements such as the combiner, harmonic filter, dummy loads or lightning protection are integrated inside the rack. The high capacity of integration considerably relaxes the space requirements for installation. This is a key factor in those locations suffering a lack of space. Considering the cost per square meter, saving space also means saving money. The exciter is ready to work with the major international TV standards: DVB-T/H, DVB-T2, ISDB-T/T B, ATSC MH/SFN. They are equipped with advanced features to accelerate the start up, ease the operation and monitoring as well as to optimize the transmitted signal. Adaptive Digital Precorrection The adaptive digital precorrection system enables the equalization of the signal easily and quickly. It can be activated manually, by a programmed trigger or it can run continuously and adaptively. The processing power of the precorrector allows to achieve unbeatable Shoulders and MER values, ensuring the highest quality in the transmitted signal. Crest factor reduction The TE9000E6 exciter offers for all OFDM standards the advantage of crest factor reduction implemented by a proprietary technology, that allows without any negative impact on MER, to reduce the signal crest factor enhancing the transmitter efficiency. TE9000 Series Exciter It integrates a HW demodulator to provide with Shoulders, MER, BER and PER values Egatel TUWH4000 Series v.1.3 3
Multiple configurations, full flexibility TSoIP inputs The exciter has an integrated Transport Stream over IP receiver able to manage two ASI streams over a Gigabit Ethernet bus. The switching between the two inputs is fully automatic and Seamless. Thus, operators get both economic and space savings avoiding the installation of an external receiver. QoS analyzer (DVB-T and DVB-T2) The TE9000E6 exciter integrates a HW demodulator to provide with Shoulders, MER, BER and PER values. This feature allows to evaluate the quality of the signal in realt time and to access this information remotely through the Web server or an SNMP client. Therefore, it saves unnecessary trips to unattended sites and the use of an external analyzer to check the output signal of the transmitter. AUWH601 Power amplifier The design of power amplifiers of the TUWH4000 transmitters family is based on LDMOS 50-volt transistors technology. They provide a compact design, high efficiency and excellent linearity, getting high energy savings. To increase the efficiency offered by Broadband Doherty configuration, the supply voltage of the transistors can be adjusted through the exciter or the control unit increasing the efficiency for all digital standards. This mechanism is considerably boosts efficiency when working at reduced power. AUWH601 Amplifier CCU9000 Control Unit Guaranted supervision The transmitters can optionally incorporate a Control Unit. This module is responsible for the controlling and monitoring of each transmitter and the redundant systems, both dual drive and N +1, as well as the air extraction system if used. It can be remotely controlled via its powerful Web Graphic User Interface or through an SNMP client. The Control Unit can be also managed locally through its high-resolution graphical display that gathers in a single window all the status information of single transmitters or N +1 systems. CCU9000 Control Unit The amplifiers are self-protected by having circuits that control the input level, output power and other critical parameters such as the temperature of the amplifier or the reflected power. The protection system automatically lowers the output power of the amplifier any time the default threshold is exceeded, preventing an amplifier damage. Those parameters, along with the values of consumption of the transistors as well as the generated alarms are sent through a data bus to both the exciter and the control unit (if any), where they can be checked at any time through the display, making the monitoring and maintenance tasks easier. They have a redundant power supply system composed by three power supplies hot-swappable from the front, so that the fault of one does not suppose any output power reduction. Each amplifier includes two fans that allow a correct transmitter operation without an exhaust air unit and an innovative cooling system that prevents air flow through the electronic components, providing full immunity to corrosion.

Quick start up and easy operation Quick start up and easy operation Instantaneous configuration via SD card Both the exciters as the control unit include an SD card to store the whole configuration of the transmitter, so the start up of a new transmitter or the configuration of a spare unit is done in seconds. It is also particularly useful to put in operation N+1 systems quickly. Powerful Web Server to manage and monitor the transmitters The flexibility and versatility present in the design of all modules is revealed once again allowing the transmitters to be fully managed through the exciter. Thus, with a single IP address is sufficient to control and monitor the status of the equipment. For this purpose, besides the SNMP protocol, the exciter integrates the most powerful and friendly Web Server on the market. The Graphical User Interface (GUI) divides the screen into two parts. All the blocks that make up the transmitter chain are shown in the upper half. A simple color coding is used to check instantly the status of individual blocks. To read or modify any parameter, just click and drag the corresponding block to drop it in the bottom of the screen, where the parameters of up to to three different blocks can be displayed. The GUI has been designed to never lose sight of the transmitter status. Exciter Web GUI Egatel TUWH4000 Series v.1.3 5
High reliability High reliability Redundant configurations The transmitters can optionally include the CCU9000 Control Unit to set up N+1 and / or dual drive redundant configurations. The extremely compact design concept allows to integrate N +1 systems in the same rack. The Control Unit is equipped with a high resolution graphical display through which is easy to locally set or change any parameter and to perform an assesment of the transmission chain at a glance. Similarly, the control unit provides remote access to the transmitters through a powerful Web GUI or via the SNMP protocol. Optimum cooling system design Redundant power supplies removable from the front panel With the aim of maximizing ease of maintenance and ensuring service availability, the amplifiers include two power supplies plus a redundant unit. In case of a power supply fails, it can be easily replaced by opening the front cover of the amplifier and pulling the faulty unit out. Furthermore, this process can be performed during the normal operation of the transmitter. Thus, by avoiding uncomfortable access to the rear part of the rack or to swtich off the amplifier, the maintenance tasks are significantly simplified without interrupting the TV service. AUWH601 Amplifier To replace any power supply just need to open the front cover of the amplifier and pulling the faulty unit out The amplifiers feature an innovative cooling system that prevents air flow through the electronic components, providing full immunity to corrosion. This is a critical point in transmitter sites located in areas with high salinity in the air. This aspect contributes greatly to increase the lifetime of the amplifiers. Each amplifier includes two fans that allow a correct transmitter operation without and external air conducting unit. Furthermore, the fans can be easily and quickly hot-swapped during maintenance tasks. Cooling system options With extraction unit. Air extraction through ducting unit installed on rear dooor Transmitters can be supplied with or without air ducting unit. In the first case, the speed of the ducting unit fans is controlled by a microcontroller according to real-time cooling needs, boosting the overall energy efficiency. No extraction unit.
